MXF files

Should I upload MXF files if I have the option ?

It's up to you, but a lot of web user's (youtubers) won't know what a MXF file format is, if you are aiming at the broadcast community than upload MXF but remember that Pond5 4K to HD scaling is converted to h.264. Is your camera MXF native? If you want to preserve your camera data in the file or SMPTE timecode use the MXF, personally I would use ProRes or DNxHD if you want to keep your footage in broadcast spec as it is a format that is familiar to a broader range of clientele, even a high bit-rate h.264 file is good enough as a storage format for stock footage, we use h.264 stock footage files in our broadcast productions and convert them to our intermediates when working with them. Most production houses here in the UK use Avid systems and footage is converted to DNxHD at the ingest stage no matter what the original file format was to begin with, and many home productions will use the native file that they downloaded from the stock site. If the production company needs a super film format so they can do deep colour grading, they will film what they need themselves.

If you are on a Windows system and you want to convert your footage to ProRes use 'Shutter Encoder' which is a good transcoding program, it's free to use, but if you find you are using it a lot please make a donation to the creator.

Thanks for that, it's really helpful, I will look into "Shutter Encoder" to convert into ProRes, I've been looking for something that would do that. Cheers

@DJGreg don't get too bogged down in video CoDecs for stock though everybody has their own preference on this :)
