On: Video editing with Python

[soegaard]

Don’t forget to check Leif Andersen’s video language

  https://lang.video/

It is a Racket language for editing videos. Quite handy when you need to edit many, similar conference videos.

I love this tool and just started using it.

If this did DNxHD codec transcoding I would love it forever. I need to ask and look to see if this is possible to add. When you edit videos you SHOULD transcode your videos into a format that actually uses one image per frame (DNxHD or PreRes (On Mac)) and than then deliver it back into a compressed format like H.264.

Yes, you should transcode your videos to an intra-frame codec (i use ProRes at 540p). But (and this is important), this is only a proxy format. When you export your creation the video editor should automatically use the original files for rendering. Premiere this very well nowadays[1].

If you have a H.264 (non-intraframed) and it is playing back in preview fine I try to just use that instead most of the time.

ProRes 540p is HUGE. Are you working with 4k? If not I would knock that down. Apple ProRes 422 is only 147 Mbs. https://www.premiumbeat.com/blog/5-things-you-should-know-ab...

540p means 540 pixels on the short side (height). That is very low res and they're not big.

Very close, UHD resolution.
