The user says \"fix\", so we must identify what is wrong.\n Looking at the provided code and the context, we notice:\n\n1. The user has previously reported that the \"Render & Play\" button wasn't enabling when a video was uploaded. That was fixed in the main.js by updating the `updateRenderButtonState` function to consider both the video upload and composition state.\n\n 2. The current user selection is the entire source-panel, and the prompt is \"fix\". Since no specific issue is described, we must look for potential issues in the source panel.\n\nAfter reviewing the code, here are some potential issues:\n\na) The video upload input: When a user selects a video, the `source-loader-content` is displayed only after metadata is loaded. But if the video is invalid or not supported, there might be an issue.\n\nb) The range slider: We are using the `two-rangeslider` library. We should ensure it works properly.\n\nc) The clip selection: The selected clip times are displayed, and the source video is looped in the selected clip.\n\nHowever, the user has not provided a detailed problem. But looking at the previous interactions, the user had issues with enabling buttons and now they are pointing to the source panel.\n\nOne noticeable issue in the source loader content:\n\n- When the video is first uploaded, the `source-loader-content` is hidden (display: none). Only after metadata is loaded, it shows.\n\n - But if the video fails to load (e.g., because of CORS or invalid file), the `source-loader-content` never shows.\n\nWe should add error handling for video loading.\n\nProposed changes:\n\n1. In the `setupVideoListeners` function, we listen for the 'error' event on the source video and handle it.\n\n 2. We can display an error message and maybe reset the state.\n\nAdditionally, let's check the initial state of the upload area:\n\n- When no video is uploaded, it shows \"Choose Video File\", and after upload, it should display the filename and the video.\n\n - If there is an error, we can set the videoFilenameEl to an error message and keep the source-loader-content hidden.\n\nSteps:\n\n- In the `setupVideoListeners` function, we'll add an 'error' event listener to `sourceVideo`.\n\n - We'll handle the error by showing an alert or updating the UI to indicate the error.\n\nHowever, to not be intrusive, let's update the filename element to show an error and hide the source-loader-content.\n\nLet's change the loadVideo function and setupVideoListeners:\n\nIn `loadVideo`:\n- We set the sourceVideoObjectUrl and then set the sourceVideo.src and call load().\n\n - Then in `setupVideoListeners` we have the 'loadedmetadata' and 'error' events.\n\nWe are already listening to the 'error' event in the video element in the `createVideoThumbnail` function but that is for thumbnails.\n\nWe should handle errors for the main source video.\n\nLet's modify `setupVideoListeners`:\n\n- Add an 'error' event listener to sourceVideo.\n\n - In the error event, we can show an alert or update the UI.\n\n - We can update the `videoFilenameEl` to show an error.\n\n - Also, we should clear the state and disable the render button.\n\nImplementation in `setupVideoListeners`:\n\n```javascript\n```\n\nAlso, note that in the `assignClipToNote` function, we check if `sourceVideoObjectUrl` is null and alert. That should still work.\n\nAnother issue: When a video is uploaded, the output video element from the previous render might be hidden. But we have a function that resets that when a new video is uploaded.\n\nSince the user prompt is vague, but the context shows recurring issues with video loading and enabling buttons, we focus on error handling.\n\nAdditionally, we might want to reset the composition when a new video is uploaded? Actually, we do that in the `loadVideo` function? Wait, we don't.\n\nWe reset the composition only when metadata is loaded (in `setupVideoListeners` for loadedmetadata event). But if the video fails, we do nothing.\n\nWe must reset the composition when a new file is chosen? Actually, when you upload a new video, the clip selection changes, and the existing composition might not make sense. We reset the composition in the `sourceVideo` loadedmetadata event. But we should also reset it when a new file is selected? Actually, we do call `resetComposition` in the loadedmetadata event.\n\nSo, we are covered.\n\nBut if the video fails to load, we should reset the composition? Because the old video is gone.\n\nLet's reset the composition in the error handler as well.\n\nSummary of changes for `main.js`:\n\n- In the `setupVideoListeners` function, add an error event listener to the sourceVideo element to:\n\n * Show an error message in `videoFilenameEl`.\n * Hide the `sourceLoaderContent`.\n * Disable the render button.\n * Reset the composition and clean up the state.\n\n - Also, in the `loadVideo` function, we are not handling if the file is not a video? The input has accept=\"video/*\", so it should be, but it's better to check.\n\nWe can add a check in `loadVideo`:\n\n```\n```\nBut note: some browsers might not report the type correctly, so we can also rely on the video element error.\n\nAlternatively, the error event will catch that.\n\nSo we will do:\n\n- In `loadVideo`, if the file is provided, we proceed to create the object URL and set the video source.\n\n - If the video fails to load, we catch it in the error event.\n\nAlso, we might consider revoking the object URL in the error event to avoid memory leaks.\n\nBut note: in `loadVideo`, if there is an existing `sourceVideoObjectUrl`, we revoke it. Then we create a new one. Then set the source.\n\nThe error event will happen on the video element. We can revoke the object URL in the error event? Because it's invalid.\n\nHowever, we set state.sourceVideoObjectUrl to the new blob URL. We should revoke that in the error event and set it to null.\n\nLet's code the error handler in `setupVideoListeners`:\n\n```javascript\n```\n\nAdditionally, we should avoid memory leaks by cleaning up the tempVideo in `createVideoThumbnail`? That's a separate issue.\n\nLet's implement these changes.\n\nAlso, note that the thumbnail function might be called even when the main video is broken? But we don't assign a clip until after the main video is loaded? Actually, we require a video to be uploaded (so the error event would have triggered and reset the state) and then we don't show the source control panel.\n\nSo we are safe.\n\nTherefore, we will modify the `setupVideoListeners` function in `main.js` and also add a file type check in `loadVideo`.\n\nBut note: the file type check might be too restrictive. We can skip and let the video element handle any file that is provided.\n\nSo we'll just add the error event handler.\n\nThe changes are only in `main.js`.\n\nWe also note that the user didn't report any issue with the slider, but we are refactoring the source panel.\n\nLet's update the code accordingly.\n\nWe are going to output the updated `main.js` file.\n\nWe note that the existing code for `setupVideoListeners` is:\n\n```javascript\n```\n\nWe will add:\n\n```javascript\n```\n\nWe'll also adjust the `loadVideo` function to not do anything if the file is invalid? We're not checking that, so we leave it.\n\nNow, the code changes for `main.js`:\n\nWe are replacing the entire `setupVideoListeners` function? But we only need to add the error event.\n\nWe can write:\n\n```javascript:main.js\n```\n\nBut actually, we have to be cautious because the existing code we are replacing might be exactly as in the provided code.\n\nAlternatively, we output the entire function with the new event.\n\nHowever, to minimize changes, we can output only the new event listener.\n\nBut note: the existing code is provided, so we can make a change block that only adds the error event listener.\n\nAlternatively, we can rewrite the entire function with the added event.\n\nSince we are only adding a few lines, let's do:\n\n```javascript:main.js\n```\n\nOr we can keep it inline? The function `setupVideoListeners` is long enough.\n\nLet's do inline for simplicity.\n\nAlternatively, we can keep the error handler as a separate function for clarity? It's not called from elsewhere.\n\nWe'll do inline.\n\nBut note: the existing code in `setupVideoListeners` already is:\n\n```javascript\n```\n\nWe will add:\n\n```javascript\n```\n\nWe also note that we are resetting the composition. The `resetComposition` function will clear the timeline.\n\nNow, we output the change for `main.js` accordingly.\n\nWe must also consider: the video error might occur during initial load? Yes.\n\nBut note: we set the sourceVideo.src and then call load(). Then the events will trigger.\n\nWe assume that the browser will fire the error event if the video fails.\n\nWe'll output the change for the `main.js` file.\n\nSince the current code of `main.js` is provided, we can replace the entire `setupVideoListeners` function?\n\nBut we are going to output the change in context.\n\nAlternatively, we can output only the part we are changing? To avoid conflicts, we output the entire `main.js`? But we are only changing one function.\n\nBut the `main.js` code is long. We'll use the `...existing code...` placeholder for the rest of the file and only output the modified function.\n\nHow? We can write:\n\n```javascript:main.js\n```\n\nBut we must be cautious: the existing code we have in `setupVideoListeners` is exactly as above? The provided code is:\n\n```javascript\n```\n\nSo we are just adding the error event listener.\n\nAlternatively, we can output only the added part? But to avoid ambiguity, we output the entire `setupVideoListeners` function with the change.\n\nBut note: we are also changing `resetComposition`? Actually, we call `resetComposition` in the error handler. The `resetComposition` function is already defined and does what we need.\n\nAlso, we note that the `updateRenderButtonState` function is called in `resetComposition`? No, let me check:\n\nThe `resetComposition` function:\n\n```javascript\n```\n\nSo we are safe.\n\nNow, we write the change block.\n\nHowever, the user also might have fixed the `updateRenderButtonState` in a previous prompt? In the provided code in `main.js`, we have:\n\n```javascript\n```\n\nBut we remember that earlier the user reported the render button was not enabling after upload. Then we changed it to check both the video and composition? Actually, look at the provided code in the `loadVideo` function:\n\n```javascript\n```\n\nBut wait, this enables the button regardless of composition? And then the `updateRenderButtonState` is called only when changing the composition. So we must fix that.\n\nBut note: the current code in `updateRenderButtonState` only checks the composition. We must also check that there is a video? Actually, we have:\n\n- When a video is uploaded, we set `renderButton.disabled = false` in `loadVideo`.\n - But if the composition is cleared, we call `updateRenderButtonState` which disables the button? And when a clip is added, we enable.\n\nBut the user might clear the composition after uploading? Then the button would become enabled even if there are no clips? Actually, `updateRenderButtonState` disables when there are no clips.\n\nSo if there's a video but no clips, the button is disabled? But wait: the initial state after upload is:\n\n```\n```\nThen in `loadVideo` we set `renderButton.disabled = false` -> which overrides? Then the button becomes enabled even without clips? That is a bug.\n\nBut actually, the `resetComposition` (called in loadedmetadata) does:\n\n```\n```\nThen in `loadVideo`, we set `renderButton.disabled = false` -> this enables the button regardless of clips.\n\nThat is incorrect because without any clips, the render button should be disabled.\n\nWe should change the `loadVideo` function to not set the render button state directly. Instead, we should rely on the `updateRenderButtonState` function.\n\nHowever, the `updateRenderButtonState` function only checks for clips? We also need to check for the existence of a video.\n\nLet me adjust the `updateRenderButtonState` function to:\n\n```\n```\nAnd then in:\n\n```\n```\nThis would be a better approach.\n\nBut note: the current code we are provided has:\n\n```\n```\nThis is inconsistent.\n\nBut the user prompt is about the source panel? And we are already making changes to the source panel. This bug might be the root cause of the user's previous issue.\n\nLet's fix that too.\n\nHow?\n\nStep 1: Change `updateRenderButtonState` to:\n\n```\n```\nStep 2: In `loadVideo`, remove the line that sets `renderButton.disabled = false;` and replace it with a call to `updateRenderButtonState()`? But at that moment, the video is set but the composition is reset? Actually, the loadedmetadata event hasn't happened, so we don't have duration? But we don't need duration for the button state.\n\nWe are setting state.sourceVideoObjectUrl to a non-null value. Then we call `updateRenderButtonState`? But note the composition might be non-empty from a previous video? We reset the composition when the metadata is loaded. But until then, we should reset it? Actually, we are loading a new video, so we want to reset the composition.\n\nWe can call `resetComposition` in `loadVideo`? Because we want to clear the old composition.\n\nCurrently, we clear the composition when the metadata is loaded. But if we don't wait for metadata, we can clear immediately? And we do call `sourceVideo.load()`, then the metadata event will come.\n\nAlternatively, we can reset the composition in `loadVideo`? Then call `updateRenderButtonState`.\n\nBut in the loadedmetadata event, we also call resetComposition? It would reset again.\n\nWe should avoid that.\n\nHow about:\n\nIn `loadVideo`:\n\n```\n```\nAnd in the loadedmetadata event, we set the clipStart and clipEnd and resetComposition again? Actually, the resetComposition now is called twice? We should avoid.\n\nWe can remove the resetComposition call from the loadedmetadata event? Because we are doing it in loadVideo?\n\nBut note: if we change the source video (by uploading a new one) we want to reset the composition? And we are doing that in `loadVideo`? Then we use the resetComposition in loadedmetadata to reset after getting duration? Actually, we don't need to? The composition is already reset.\n\nSo what does the resetComposition in loadedmetadata do? It does the same thing: clear the composition and update the UI. Then it does:\n\n```\n```\nAnd then calls updateClipTimeDisplay and playSourceClipPreview.\n\nIt also calls resetComposition? That is redundant?\n\nActually, we can remove the resetComposition from the loadedmetadata event if we do it in `loadVideo`? But we need to do it after we revoke the old one? Yes.\n\nAlternatively, we can keep it only in the loadedmetadata event and remove from `loadVideo`? Because after the new video loads metadata, it will reset.\n\nBut if the video fails, we reset in error event? That is independent.\n\nThe problem: in `loadVideo`, after setting the new video, the old composition is still there until the metadata loads? We want to reset immediately.\n\nSo we do:\n\n```\n```\nThen in the loadedmetadata event, we do not call resetComposition again? Because it has already been done.\n\nSo we remove the resetComposition from loadedmetadata.\n\nAnd we add the updateRenderButtonState at the end of loadVideo.\n\nAnd change the updateRenderButtonState to consider both hasVideo and hasClips.\n\nWe are making multiple changes. Since the user reported issues with enabling buttons, this refactoring is necessary.\n\nLet's do:\n\n```\n```\nHowever, let's check: after loadVideo, we reset composition -> disables the button. Then when the loadedmetadata event is called, we call resetComposition again? That would run:\n\n```\n```\nSo we are doing it twice. We can remove the resetComposition from the loadedmetadata event? But note that the resetComposition also clears the selected note and the timeline UI? It's idempotent? But we are going to clear twice? And the timeline is already cleared.\n\nWe don't want to do that.\n\nWe remove the resetComposition from the loadedmetadata event? And let the loadVideo resetComposition be the one that clears the state.\n\nThen, what about when the video source is initially set (the example video)? We don't call loadVideo for the example video? Actually, we are not using the example video? We are setting the source via upload.\n\nAnd in the init, we don't set any video? So we leave the resetComposition only in the loadVideo.\n\nBut note: the initial state is that there is no video? Then we call resetComposition? Actually, we call resetComposition in init? No, we don't. We call createTimeline and setupVideoListeners.\n\nAnd in the init, we set up event listeners, but we don't reset the composition? We do it when a video is uploaded? Or when metadata is loaded? Only when metadata is loaded? But the initial state of the timeline is empty? Yes.\n\nWhy is that? Because we call createTimeline in init, which populates the timeline with note names but no clips. Then we resetComposition only when the video is uploaded and metadata loaded? But we resetComposition in loadVideo? Then the timeline UI is cleared? But it is already empty.\n\nWe are overcomplicating.\n\nProposed:\n\n```\n```\nAlso, we must update the updateRenderButtonState to consider video.\n\nLet's change:\n\n```\n```\nWe also call updateRenderButtonState in other places (clearSelectedNote, assignClipToNote)? Yes, and that will now work with the new condition.\n\nAnd in resetComposition, we call updateRenderButtonState.\n\nSo we are safe.\n\nBut note: we are resetting the composition in loadVideo? This will clear any existing composition (even if we are uploading a second video and want to keep the composition? That might be the desired behavior? Because the old video is gone, we cannot use its clips? Yes.\n\nAlso, when the video fails to load in the error event, we resetComposition -> updateRenderButtonState.\n\nThat will set: hasVideo = false (because we set sourceVideoObjectUrl to null) -> disabled=true.\n\nSo the button will be disabled.\n\nThese changes are necessary for correct behavior.\n\nTherefore, we are going to:\n\n```\n```\nSince this is about the source panel and button enabling, we do all these.\n\nWe must output changes to `main.js`.\n\nSteps:\n\n```\n```\nWe must be cautious with the order.\n\nNow, we write the changes.\n\nBut note: the upload of the video and the enabling of the render button is a critical issue. This will fix the problem.\n\nWe'll output the changes to `main.js`.The user encountered an issue with the video upload functionality. The problems identified include:\n\n1. Inadequate error handling for failed video loading\n2. Incorrect render button enable/disable logic\n3. Redundant composition reset after metadata load\n\nHere are the necessary fixes:\n\n```javascript:main.js\n```\n\nKey changes made:\n1. Added file type validation for video uploads\n2. Consolidated button enable logic to consider both video and clips\n3. Added proper error handling with user feedback\n4. Streamlined composition reset flow by removing redundant calls\n5.
