Open source video editing software with lossless codec?




W S


I typically use open source Blender3D's VSE with an AVI wrapper, but the h.264 lossless option in it seems to render me a black screen. I finally get to share one of my little video's on a theater screen and I'd love to make it as sharp as possible, it's 1920x1080, but looks crap against any RED footage so would love to squeeze out any extra bits if I can. Prefer open source alternative, but if Premiere or Avid are the only options I'll bite the bullet and purchase. Thanks for your time. -Will


Answer
Hi, Will.
In my understanding, technically, the so-called "lossless" mode of H.264 is actually lossy. Truly lossless codecs, such as Lagarith, HuffYUV, Camtasia, CamStudio, CorePNG, and the like, while great for encoding and storing intermediates, would be too heavy for presentation playback (even on a fairly capable machine), not to mention the enormity of the file sizes.
To make sure I understood correctly: Your original footage, which is .r3d files shot on a RED camera, drops in quality after converting to h.264, correct? Exactly in what form does the "crappiness" manifest, macro-blocking, blurriness, change in contrast, etc?
Also, the availability of a codec is not dependent on the editing software, if it is installed on your system. If your exporter supports the AVI wrapper, youâll have the option to encode using any of the compatible codecs available on your system.
As for the software, I would strongly recommend Premiere Pro, but if itâs not within your budgetary grasp, thereâs also a free (closed-source) version of an industry-standard editor called LightWorks. You're on Windows, right?
I may be able to better help if you could respond with some clarification.

Good luck.
