Frequently Asked Questions
- What video formats can FileCrank convert?
- FileCrank accepts MP4, MOV, WebM, AVI, MKV, FLV, WMV, and OGV as input. Output formats include MP4 (H.264), WebM (VP9), MP3, and GIF. The Video to MP4 tool is the most versatile β it accepts all of the above input formats.
- What is the maximum video file size?
- Most video tools accept files up to 500 MB. The Video to GIF tool is capped at 200 MB. Video Merge accepts up to 300 MB per clip with a maximum of 10 clips. If your file is larger, compress it first with the Video Compressor tool.
- Is video processing private?
- Yes. Files are uploaded over HTTPS, processed on FileCrank servers, and automatically deleted within one hour. No account or signup is required. FileCrank does not retain or analyse your video content.
- Can I trim a video to a specific start and end time?
- Yes β the Video Trimmer tool lets you set a precise start and end time in seconds. It uses stream copy where possible (no re-encoding), which makes trimming fast and lossless for compatible formats.
- How do I reduce video file size without losing quality?
- Use the Video Compressor tool. It uses CRF (Constant Rate Factor) encoding: "High quality" (CRF 20) produces larger files with better quality; "Medium" (CRF 26) balances size and quality; "Low" (CRF 32) gives the smallest file with the most compression. For most use cases β email, social media, messaging apps β Medium is the best starting point.
- What video format does YouTube accept?
- YouTube accepts MP4, MOV, AVI, WMV, FLV, WebM, and MKV. The recommended format is MP4 with H.264 video encoding and AAC audio at 44.1 kHz. Use the Video to MP4 converter to prepare any video for YouTube upload.
- How do I add subtitles to a video?
- Use the Add Subtitles tool. Upload your video and a subtitle file in SRT or VTT format. The tool burns the subtitles directly into the video frames (hardcoded subtitles), so they are always visible regardless of the player or platform. This is the most compatible approach for social media and messaging apps.
- How do I extract a thumbnail from a video?
- Use the Video Thumbnail Extractor tool. Upload your video, specify the timestamp in seconds, and download the extracted frame as a high-quality JPG or PNG. No video editor or screen capture required.
