FAQ / Tips and Tricks   Q: I’m shooting 4k for a HD 1080p or 1080i project, what are the best conversion settings? A: Go to “Conversions” panel, and select “Video Resample” to “HD 1080”, this will produce a crisp 1080 video, keeping the detail without oversharpening. For 1080p, just leave “frame rate conversion” to 24p, NTSC 30p or 60p, or PAL 25p or 50p. For 1080i, set “frame rate conversion” to 30i/60i for NTSC and 25i/50i for PAL. TIP: for conversions to 60p/60i or 50p/50i it is better to shoot 4k at 60p or 50p. Q: I want to convert 4K and HD videos to 24p frame rate, but keeping the original dimensions A: Just select “Convert to 24p” and leave the “Video Resample” setting as “no video resample”. Q: I want to convert 4k and HD videos to HD, but keeping the original frame rate A: Select “HD 1080” in “Video Resample”, and leave the frame rate conversion setting as “No frame rate conversion”. Q: I've recorded several files in 1080i and 720p, how can I process them separately? A: Simply Select the videos to process using current settings, and send a batch to process, then change the settings and send another batch. Q: Using a rewrapping mode gives video error or generates a non valid video A: Intertake always tries to create the rewrapped video if there are no start errors, however rewrapping videos some codecs/wrapper combinations may generate errors, for instance if the packets time stamps are not correctly set. In this case you can try by transcoding the video. Q: I want to set a color correction and LUT separately for each video A: Just go to color tab and check “Set color correction for selected videos” button, then open color correction and set the options. Q: I want to apply a LUT to all the videos in the list A: Just go to color tab and check “Set color correction for all videos” button, then open color correction and select the LUT, or simply select a favorite LUT in the color tab and activate it. Q: Why shutter speed and aperture don't appear on metadata information? A: Depending on the camera manufacturer, shutter speed and aperture information can be available in video files. If your camera include this information then Intertake 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 DNxHD. 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 Cineform, 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: With some video cameras, when processing some full HD videos (1920x1080) in PAL mode, the processing is not  correct. A: When recording in 1920x1080 in PAL mode (FULL HD mode), some cameras flag the videos 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.  Intertake tm  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.
