[18 hours] llm cmd Tool: Simonw uses the llm-cmd tool for generating FFmpeg commands via LLMs.
[31 minutes] Custom Bash Function: pmarreck created a bash function called please that uses an LLM to generate and display FFmpeg commands before execution.
[18 hours] LLM Command Complexity: Resonious found that LLMs sometimes generate overly complex and failing commands due to missing libraries, requiring user oversight.
[10 hours] Source File Awareness: cm2187 points out the need to understand source file formats (audio/subtitle tracks, etc.) to craft correct FFmpeg commands. Also mentioned a recent change in FFmpeg behavior that requires a workaround.
[3 hours] ffprobe + LLM: Philpax suggests using ffprobe output to clarify file details when generating commands via Claude.
[Multiple times] AI-Generated Man Pages: Several users discussed using AI to generate man pages, some are already doing this.
[Multiple times] LLM Limitations: Some users have reported LLMs giving wrong information, or being out of date, including an example of a wrong time for a football game.
[16 hours] LLM Technical Questioning: sdesol suggests using models like Sonnet 3.5 and DeepSeek V3 for technical questions over GPT models.
[13 hours] Current LLM Model Landscape: A user (wegfawefgawefg) notes that GPT-4 is outdated and that '01mini' is better, faster, and cheaper and that the next model 'o3/o3mini' is coming soon, and shares examples of complex bug detection done by newer models.
[14 hours] libx264 Importance: jack_pp explains that libx264 is a crucial encoder for h264, so those commands that include it are standard.
[Multiple times] LLM Specialization: Users suggested that specific LLMs may be better for certain kinds of prompts. Also discussion about LLMs that choose the optimal seconday LLM for the task.
[Multiple times] The "Perfect" Model: There is some discussion about the impracticality of having a model that works without fail for every task in ffmpeg.
[Multiple times] Learning Regex vs Using LLMs Users discuss that while learning regex is a useful skill that saves time, it is a skill that requires specific and often arcane knowledge that an LLM can fill in for, giving 70% of the value with no learning cost.
[Multiple times] Regex Escaping Issues: codetrotter points out the complexity of regex escaping rules with different tools.
[Multiple times] FFmpeg as a complicated tool: Many users recognize the complexity and depth of knowledge required to learn ffmpeg.
[17 hours] FFmpeg Needs a Better Interface mrweasel suggests that ffmpeg needs an improved CLI.
[Multiple times] User-Respecting Open Source: hnuser123456 draws parallels between code and AI tools, emphasizing the value of open-source tools that respect user control.
[16 hours] LLM as Autocomplete: Waterluvian is persuaded to add LLMs as a helper tool, describing it as the most epic autocomplete.
[15 hours] Persistence & Creativity: Over2Chars argues that the struggle with learning tools like FFmpeg fosters persistence and creativity.
[Multiple times] Avoiding Over-Reliance: hbn acknowledges the need to balance using LLMs and still practice problem-solving skills.
[20 hours] ChatGPT Solving FFmpeg and Regex: levocardia shares that LLMs have made learning complex tools like regex and FFmpeg easier.
[Multiple times] FFmpeg Syntax: Users note that many FFmpeg flags are order-dependent and not user friendly.
[Multiple times] GUI Alternatives: Some users mention GUI-based tools, like Handbrake, as an alternative to the command line.
[Multiple Times] GPU Encoding vs Software: Users note that hardware encoding via GPUs can produce significantly lower quality than software. Though GPU encoding is suitable for real time and live use-cases.
[20 hours] Scene Detection: jazzyjackson describes using scene detection in FFmpeg to digitize home videos.
[18 hours] Empty Scene Detection: dekhn uses FFmpeg to detect and remove empty frames from video recordings.
[18 hours] Raw Video Capture: dekhn describes using FFmpeg to capture and compress raw video from a microscope.
[Multiple times] FFmpeg Python Libraries: Several users mention ffmpeg-python and similar tools for programmatic command line composition.
[Multiple times] FFV1 for Lossless Encoding: jcalvinowens recommends using FFV1 for lossless YUV encoding, though another user notes it may not be much better than libx264.
[Multiple times] Ramdisks: Users mention ramdisks as an ideal way to handle intermediate steps in video processing.
[20 hours] Static FFmpeg: joshbaptiste advocates building FFmpeg statically, and links to a containerized version.
[Multiple times] FFmpeg as a Memorization Challenge: Many users express that they have trouble remembering complex FFmpeg syntax.
[Multiple times] LLM Integration with Terminals: Users discuss using LLMs directly in terminals, and mention tools like Warp for this.
[20 hours] Custom Notes: Many users have their own notes or reference guides for FFmpeg syntax.
[Multiple Times] Combining Multiple Videos and Subtitles: A user had trouble combining multiple videos and including subtitles, and mentions that this was not an example they found on the site.
[Multiple times] FFMpeg Cheat Sheets: Several users shared links to their FFmpeg cheat sheets.
[Multiple times] Gstreamer: Many users mention gstreamer as an alternative that may have a more sane architecture.
[Multiple times] The FFmpeg Filter DSL: A user notes that FFmpeg's filter DSL is very useful.
[15 hours] FFmpeg Book: AdieuToLogic shared a link to a github repo for an FFmpeg ebook.
[11 hours] Text Output to STDOUT Peter_retief pointed out a broken example on the site. The issue was that the text encoding method was no longer supported on current versions of FFmpeg, and this was fixed.
[Multiple times] The Need for an FFmpeg UI: Several users commented that a GUI-like interface is what FFmpeg needs.
[18 hours] LLMs for Docs: karpathy suggests writing documentation for LLMs instead of humans.
[Multiple times] FFmpeg as "Insane": Some users consider FFmpeg to be a very powerful but obtuse and complex tool.
[17 hours] Including Files in Filters: somat points out that it is possible to include files directly as filters instead of tangling everything inline.
[Multiple times] The FFmpeg By Example Site Many users find the site useful but also bring up several criticisms, including: The first example being overly complex, the lack of ordering of the examples, the upvote system not working, and the "try online" button not working.
