Mirror flip .mpeg before editing ! (Brevis problem)

[Hyacinthe Carle]

Hi everyone.

We recently shot a relatively long action sequence on Canon XH-A1 and an equivalent of a Brevis35 system.
This system records through a mirror, resulting in upside-down images.

I am using Premiere. Is there a way to flip the video source before editing ? Lossless of course ?

Here's the source :

File Path: Sequence01.mpeg
Type: MPEG Movie 
File Size: 10.2 GB
Image Size: 1440 x 1080
Pixel Depth: 32
Frame Rate: 23.976
Source Audio Format: 48000 Hz - compressed - Stereo
Project Audio Format: 48000 Hz - 32 bit floating point - Stereo
Total Duration: 00:54:17:10
Average Data Rate: 3.2 MB / second
Pixel Aspect Ratio: 1.3333

Cheers !

no. there is no lossless way to flip/invert footage. it has to be re-encoded to the new orientation. the quality loss can be minimized by encoding to a uncompressed or lossless codec. maybe try the cineform neoHD or neoscene codec(not free) for use with premiere.

can't you just apply vertical flip and horizontal flip effect in premiere ?

You say 'there's no lossless way to do it', but you suggested a lossless codec... I don't understand . I don't mind re-encoding.

I tried that, but the sequence has to be on the time-line, which is annoying for a rough assembly.

sure, you can flip it in avisynth and encode to uncompressed or a lossless format (e.g huffyuv, lagarith, ut video codec, all free)

these are harder to edit (slow unless you have fast system) , that's why aedipuss suggested cineform , which is minimally lossy and provides better performance for editing, even on older computers

if you want something easier to use, or are not familiar with avisynth, maybe something with a gui like avidemux should be able to do what you want as well

another approach is to nest sequences (e.g. flip the clips in their own sequence and re-import the sequence into a new sequence)

I can flip the movie fine with Adobe Premiere , what I need is a way to export that. NeoHD sounds fine, but the trial has a watermark and I'm not ready to blow my budget on 1 codec for an hour of footage. Huffyuv and Lagarith are apparently not HD codec (at least not with Adobe Media Encoder).
Or did I miss something ?

Nesting sequences is the last solution .

[poisondeathray]

huffyuv and lagarith can be HD, you just have to set it up in AME to match your sequence settings

lagarith will be a pain to edit , but smaller filesize (more compression)

BTW :
Nesting was the solution.

Thank you !
