FootageStudiotm FAQ / Tips and Tricks
Q: I've recorded several files in 1080i and 720p, how can I process them separately?
A: Select the videos to process using current settings, and check the button "process selected files".
Q: when selecting backup original files, does FootageStutiotm delete the files on the card after the backup process?
A: no, due to security reasons, FootageStutiotm never deletes any file on the memory card. Even if you habilitate the backup option, after the backup you must
delete manually the videos or format the memory card.
Q: Why shutter speed and aperture don't appear on metadata information?
A: Depending on AVCHD and HDV camera manufacturer, shutter speed and aperture information can be available in video files. If your camera include this
information then FootageStudio extracts it and adds it to metadata text.
Q: Why DxnHD codec gives an error when encoding at 1440x1080 pixels?
A: DxnHD codec does not support 1440x1080 pixels, to use this codec you must rescale to 1920x1080 or 1280x720 pixels. See codecs for more information about
Q: The videos are saved correctly but they cannot be opened in other applications.
A: The codecs used to record the videos must be installed in your system, to download the codecs please go to the codecs section.
Q: When selecting “no audio” and “extract Audio”, after loading the result files on my NLE the video and audio durations don’t match.
A: If the lenght of the video is changed when selecting framerate conversions, the audio must be resampled to match the new duration. The “extract audio” funcion
saves the original audio without resampling. To resample the audio contained in the video file uncheck the “no audio” option.
Q: After Denoising a video, I get a noisier video than I see on the denoiser preview when saving in MJPEG.
A: If you plan to edit or store a denoised video, it is recommended to use a pro format to save it, like DNxHD (or ProRes) in 8-bit or 10-bit, or also a lossless codec
like L-JPEG or V210.
Q: After importing a video, the video parameters like progressive/interlaced or aspect ratio are wrong
A: It may happen if the video is damaged or incorrectly stored, just select the video and click right button, then select “interpret video” and enter the correct data.
Q: I want to save the video information like resolution, bitrate, aperture, etc if available
A: Just open the options dialog and check “create a text file with video information”, then a info text file will be created with the same video name.
Q: When using GPU for processing, I get occasional crashes.
A: Some GPU cards could crash on certain processing settings, just try to check “Max Compatibility” in GPU options.
Q: I plan to use overcrank feature, how can I the get best overcrank quality?
A: To get a better overcrank results it is advisable to record a low blur video, using at least 1/100 or 1/120 shutter speed.
Q: Some progressive videos are incorrectly processed as interlaced
A: Some cameras don’t set the interlaced flag correctly. If you want to process interlaced videos detected as progressive, please set “interpret footage as”
“progressive” in “interpret video as” dialog. If progressive videos are detected as interlaced, set “interpret footage as” “interlaced.
Q: When processing PANASONIC GH1 full HD videos (1920x0180) in PAL mode, the processing is not correct.
A: When recording in 1920x1080 in PAL mode (FULL HD mode) , the videos are marked as 50 FPS interlaced, however the correct video format is 25 FPS
progressive. To process correctly these videos please open the "INTERPRET VIDEO AS" dialog and set the videos as "PROGRESSIVE".
Q: After capturing from my HDV camera and processing the files, what happens with intermediate HDV files captured from tape?
A: if you check "keep original files" on capture program, then the m2ts source files will not be deleted after the processing. If not, all the intermediate captured files
will be deleted after processing, and you must capture it again from camera tape if you want to reprocess them.
Q: What are SuperWhites?
A: Some camera manufacturers break the video standards to get more white levels when viewing the videos on a TV. The TV levels range is 16-235, but these
cameras store also information on upper levels, this is, using a 16-255 range. When processing using normal TV levels this extra dynamic range is lost.
Q: When selecting “PC levels” and SuperWhites the video contrast is too strong.
A: This is usually a codec or NLE problem. Some codecs and NLEs asume “Video levels” by default cropping the upper and lower levels. It may be solved
configuring the codec by pressing the button “configure” after selecting the external codec. On your NLEs configure it correctly or use the PC<->TV levels setting.
Q: How to configure the PC<->TV levels setting to avoid clipping or washed out colors?
Usually video cameras record video using TV levels, this is the color range goes from 16-235, and other cameras like canon HDSLRs record video with PC levels
using a 0-255 range. If you edit a 0-255 levels range video in your NLE using a TV 16-235 range, you are losing valuable dynamic range or getting washed out
colors. Also, many video cameras “officially” using TV levels 16-235, are in fact using a levels range 16-255 to increase video quality, and when editing in TV range
you are clipping the valuable information stored in 235-255 levels range, the so called SuperWhites. FootageStudiotm can avoid colors washed out and color
clipping, providing a video with the full levels range preserved ready to edit.
To configure levels setting:
-if you will edit the video using TV range 16-235:
- if you camera uses the normal TV range, leave all unchecked.
- If your camera uses the TV range plus superwhites, this is 16-255, check TV>TV and superwhites.
- If your camera uses PC levels, check PC>TV
-If you will edit the video using PC range 0-255:
- if you camera uses the normal TV range, select TV>PC
- If your camera uses the TV range plus superwhites, this is 16-255, check TV>PC and superwhites.
- If your camera uses PC levels, leave all unchecked.
