Quarter installation

I spend a lot of time traveling. The laptop is always with you, but it is not always possible to work creatively. But the installation is the most it. In editing, the most time consuming viewing of the material and study of the joints of the scenes. This is especially true of "raw", "elemental" material. When there are a lot of duplicates, there is a lot of marriage in duplicates and you have to sew a video in literally the only possible way.

What a bad luck: my laptop ASUS UL30A, does not drag high-definition video in your favorite Sony Vegas , when working on batteries. I am silent about FullHD.

A small but useful trick under the cut.

Source Parcels:

1. The viewing window on a laptop, even when using a second USB monitor, is significantly less than the hayres
2. A lot of resources are spent on decoding "advanced formats" H.26x
3. When the montage (in this case, Vegas) does not cope with the flow, it solves the problem of skipping frames, which in the case of thin montage creates problems

')

Conclusion:

Can and should be used for editing (at least in the first stage) video in low resolution (size), with minimal compression and the same frame rate as the original.

Usage scenario:

• We pinch the video to a lower resolution (I use 1/4 HD - 640x360, by the way, with this resolution I am also mounted on a powerful home computer: there are no glitches with frame transmission, and the details are visible enough)
• Downloaded video we put in a separate folder
• Mounted in it
• At the end of the installation, we change the project parameters (frame size) We initially set the project parameters in the output resolution - this does not affect the performance, but allows using Pan / Crop / FX, etc. (thanks to Laplace and merlin_rterm)
• And calmly copy the source materials into the folder with “compressed video”. Vegas normally picks them up. Or use Replace in ProjectMedia (maki)

Technical implementation:

For batch compression, I used ffmpeg . Through trial and error, the mpeg4 codec was chosen as the leader in terms of size / quality ratio, and joyfully met by vegas of all versions.

A little shamanism with the cmd file (I haven’t written bat for a long time) and the running script creates a short subdirectory in the source directory with a copy of the source files in a quarter-size.

rem 2short.cmd
mkdir short
for %%i in (*.mov) do (
ffmpeg -y -i %%~ni.MOV -s 640x360 -vcodec mpeg4 -b 5000000 -ab 128000 short/%%~ni.MOV
)


Ffmpeg parameters used:

• -i - source file
• -y - overwrite the output file (last parameter) without confirmation
• -s - frame size
• -vcodec - used codec
• -b - video bitrate
• -ab - sound bitrate

Proof:

A spontaneous project - shot in one and a half days of shooting, in seven lokas, without elaborated storyboards of the final scenes, on whale optics Cannon 7D (professionals will curse me). The project was mounted for more than six months due to the confusion of the material (sometimes it seemed that the material could not be saved). It is in the quarters.
