| if you could write frames back into the container to overwrite existing ones I don't think I'd mess with img sequences again for render intense projects where they work better. you'd have to put it there of course before any app could do that, but it would be a huge benefit to have and gain usage.

Most filesystems support hard links where one file is actually pointing to another file, but as far as I know it is always the whole file.

The MXF container supports some level of cuts-based editing like you have in QuickTime. I'll have to dive in there to see how feasible it is, and then there's the problem of getting applications to actually support that feature. > > >> GrassValley has a DNxHD/ProRes/CineForm/Dirac(?) flavour of their own called HQX that is quite comparable in quality to those others, but is without many of the restictions of them, and they made it free for all recently. > > > Yes, I am aware of HQX and it seems like a really good codec. You can download the codec for free, but it is not open source and I feel like Grass Valley has no intention of making it so. Once we get this project going, I suppose it wouldn't hurt to ask them though. |
